Embodiment

[0016] Example: A photosensitive antiviral textile, comprising a photosensitive dye, a polyacrylic acid layer and a crosslinking agent, the crosslinking agent combines the polyacrylic acid layer with the surface of the textile, and the crosslinking agent combines the photosensitive dye with the polyacrylic acid layer , the chemical structural formula of the photosensitizing dye meets the following general formula (A),

[0017]

[0018] Wherein at least one of the substituents R is one of hydroxyl, carboxyl, amino, alkene, mercapto and other similar active groups.

[0019] Under light conditions, the photosensitive antiviral textile can absorb photons and react with the surrounding oxygen to generate singlet oxygen, and singlet oxygen can oxidize and destroy phospholipids and proteins, thereby destroying the envelope of the virus and inactivating the virus. For proteins, the target amino acids for oxidative destruction by singlet oxygen are tryptophan, histidine, tyrosine, c...

Abstract

The invention discloses a photoconductive antivirus fabric and a manufacture method thereof. The photoconductive antivirus fabric prepared by the method comprises a photosensitive dye, a polyacrylic acid layer and a crosslinker and can absorb photons and act with surrounding oxygen to generate singlet oxygen under the illumination condition, the singlet oxygen can be oxidized to damage phospholipid and protein so as to damage a viral envelope and deactivate viral activity. For the protein, target amino acids to be damaged by the oxidized singlet oxygen comprise tryptophan, histidine, tyrosine, cysteine and methionine. The photoconductive antivirus fabric also acts on gram-positive bacteria and thus has the anti-virus and anti-bacterial action.

Description

technical field [0001] The invention relates to a textile with antivirus and antibacterial functions and a manufacturing method thereof. Background technique [0002] The flu virus is the only virus that spreads as an aerosol when a sick person sneezes. During the epidemic season, it can spread rapidly around the world. The World Health Organization estimates that the medical expenses caused by influenza amount to hundreds of millions of dollars each year, and influenza causes 250,000 to 500,000 deaths each year. And the occurrence of avian flu shows that there is still no effective way to deal with the occurrence of large-scale influenza. Immunization can effectively reduce the incidence and severity of influenza, but due to the rapidly mutating nature of influenza viruses, new vaccines must be produced every year. Restricted by time and vaccine production methods, it is difficult to ensure that there are enough vaccines for use during the influenza epidemic season every...
